Abstract
The utility model relates to a lock controlled by a motor, which is characterized in that a ratchet, a pawl, a worm gear and a worm are positioned among a hand shaft, a bolt and a motor. The lock takes use of the on-off controlling lock of the ratchet and the pawl to control locking and unlocking the lock. The power of the motor is transmitted by the friction force generated by the worm gear, the worm and the friction pieces on the worm gear so as to ensure the mechanism can operate steadily.
Description
The utility model relates to the lock of a kind of lockset, particularly a kind of Motor Control.
The electric control lock of Xiao Shouing mainly is made up of handle, motor, screw rod, swing steel wire, latch and dead bolt in the market, during the rotation of motor drives screw rod, swing steel wire on the screw rod produces swing, in the parts that latch inserts with handle links to each other, handle can not be rotated, dead bolt does not bounce back, and promptly door is lockable.Its defective is: when 1, rotating handle by force, the parts of the prevention handle rotation that latch links to each other with it will be destroyed, and then make dead bolt produce retraction, so theftproof performance is poor.2, motor drives swing steel wire and latch motion, motor can not stop the rotation at once after the latch motion puts in place, and the swing steel wire will produce on screw rod beats, and moves not steady.
The purpose of this utility model is the lock that a kind of Motor Control will be provided, and the strong and motor of its theftproof performance operates steadily.
The utility model is achieved in that ratchet, ratchet, worm gear and worm screw is housed between handle axle, dead bolt shifting block and motor.Ratchet is contained between handle axle and the dead bolt shifting block, and ratchet is contained on the dead bolt shifting block.Friction member and swinging axle are housed on the worm gear, and friction member is pressed on the swinging axle, makes them keep CONTACT WITH FRICTION, and the end of swinging axle is fixed with swing arm, and the free end of swing arm links to each other with ratchet.When motor rotated to a certain direction, worm screw drove the worm gear rotation, and worm gear drives the swinging axle rotation by the stiction between friction member and swinging axle, makes swing arm put an angle, and ratchet produces deflection and and ratchet engaged.After engagement process stops,, at this moment will produce slip between friction member and the swinging axle, to guarantee that motor steadily drives worm and worm wheel and rotates to the time of setting and stop if motor is still rotating.The operation handle, rotatablely moving of handle axle passes to the dead bolt shifting block by ratchet and pawl, and the dead bolt shifting block retracts dead bolt in the lock body by the dead bolt sliding panel, and lock is opened.When motor rotated to other direction, pawl-and-gearing separated, and the handle axle can not transferring power, and handle is in idling conditions, and lock is lockable.
The utility model is because the engagement and the motor of employing ratchet and ratchet come transferring power by friction, so theftproof performance is strong and mechanism's stable working is reliable.
Accompanying drawing is the longitudinal sectional view of the utility model embodiment.
With reference to accompanying drawing, in lock housing (16), dead bolt shifting block (13), ratchet (10), ratchet (12), worm gear (2) and worm screw (1) are housed between handle square shaft (9) and the motor (15).Ratchet (10) is contained between handle square shaft (9) and the dead bolt shifting block (13), and ratchet (12) is contained on the dead bolt pulling block (13) by axle (11).Friction member (3) and swinging axle (5) are housed on the worm gear (2), and go up shock mount (4) at friction member (3), the other end of spring (4) withstands on the inner chamber of worm gear (2) and guarantees friction member (3) and swinging axle (5) CONTACT WITH FRICTION.Fix a swing arm (6) in the end of swinging axle (5), when unblanking, the worm screw (1) of motor (15) drives worm gear (2) rotation, worm gear (2) drives swinging axle (5) rotation by the stiction between friction member (3) and swinging axle (5), make swing arm (6) put an angle, ratchet (12) meshes with ratchet (10) after axle (11) produces deflection.After engagement process stops, worm gear (2) continues rotation, at this moment will produce slip between friction member (3) and the swinging axle (5), to guarantee that motor (15) steadily drives worm screw (1) and worm gear (2) and runs to the time (determined by test the duration of runs of motor) of setting and stop.Then, operation handle (not drawing among the figure), the engagement that rotatablely moves by ratchet (10) and ratchet (12) of handle square shaft (9) passes to dead bolt shifting block (13), dead bolt shifting block (13) overcomes the elastic force of spring (14) by dead bolt sliding panel (8), dead bolt (7) is retracted in the lock housing (16), and lock is opened.If motor (15) is to the other direction rotation, ratchet (12) separates with ratchet (10), and during the operation handle, handle square shaft (9) drives ratchet (10) idle running, and lock just can't be opened.
Claims (4)
1, a kind of lock of forming by handle axle (9), dead bolt shifting block (13) and motor (15), it is characterized in that being equipped with between handle axle (9), dead bolt shifting block (13) and the motor (15) ratchet (10), ratchet (12), worm screw (1) and worm gear (2), ratchet (10) is contained between handle axle (9) and the dead bolt shifting block (13), and ratchet (12) is contained on the dead bolt shifting block (13).
2, lock according to claim 1 is characterized in that being equipped with on the worm gear (2) friction member (3) and swinging axle (5) and friction member (3) and swinging axle (5) and keeps CONTACT WITH FRICTION.
3, lock according to claim 1 and 2 is characterized in that swing arm (6) is equipped with in the end of swinging axle (5).
4,, it is characterized in that the free end of swing arm (6) links to each other with ratchet (12) according to claim 1 or 3 described locks.
